Price Estimation Please (1994 Laphroaig)

Hello,

I was recently given a limited edition bottle of laphroaig and was wondering if you could help me identify it, and give me an idea of its worth today.

The bottle is clear, and it has a white label which says on it;

Laphroaig
Single Islay Malt Scotch Whiskey
1994
The most richly flavoured of all scotch whiskies
Established 1815
Islay festival of malt and music 2006
Cask filled by John Campbell (apprentice 1994)
Hand bottled by John Campbell (distillery manager) 2006
at natural cask strength, for the Feis Ile 2006.

70cl / 56%

any information would be much appreciated.
